The first affixing means may be part of a zipper or a hook and eye, or the shape of the footwear itself by using adaptable silicone shells or magnets, while the second affixing means are the supplementary means of the former. The first affixing means, in the case of the zipper, may be arranged on the sole or on the cut of the footwear. Coupling different shells with different ornaments, designs and/or colors is easily achieved with the invention.

OBJECT OF THE INVENTION

The present invention may be encompassed in the technical field of footwear, and more specifically, in terms of typical elements and accessories for footwear and the components thereof.

The main object of the present invention is footwear that stands out mainly because it incorporates a base body and shells coupleable to the base body that may be exchanged, allowing the coupling of different shells to the same footwear with different designs, materials, models, and/or colors.

BACKGROUND OF THE INVENTION

When a user is interested in footwear of a specific design, material, or color, he or she needs to acquire a different footwear model according to his or her tastes, with the subsequent cost that the acquisition of each piece of footwear implies.

Another inconvenience that should be highlighted is the large amount of space required by all the shoe models each person has in his or her closet, requiring new, larger closets.

A further inconvenience related to this point is the large amount of space currently required in travel suitcases to store the various shoe models, increasing the weight of said suitcases and, consequently, the possible cost thereof.

Therefore, the object of the present invention is the development of a constructive form of footwear that allows configuring different shoe models with a reduced number of base shoes, developing footwear with exchangeable shells as the one to be described below and contained in its essential points in the first claim.

DESCRIPTION OF THE INVENTION

The footwear proposed by this invention comprises a base body and an exchangeable shell, affixing means being defined in the shell and in the base body that allow coupling and uncoupling shells with different ornaments, models or colors to said base body.

The invention seeks to protect the footwear designed for the affixing of the exchangeable shells and the exchangeable affixed and mounted on the shoe. The exchangeable shells can be affixed directly to the base body or to the cut of the shoe, covering said cut, having in both cases affixing means of the exchangeable shell on the footwear, either on the base body itself or on the cut of the footwear.

In a first embodiment, the base body has first affixing means, such as half a zipper or a hook, for example, and the shells incorporate second affixing means, supplementary to the former, consisting of, for example, the other half of the zipper or an eye, intended to be coupled to the first affixing means of the base body.

Different embodiments have been envisaged, since the base body may be configured by means of a sole and a cut, the first affixing means being in the sole itself or in the cut, so the shell would be coupled in an enveloping arrangement to the cut, the closure being established by means of the coupling of the second affixing means to the first affixing means.

Another possibility contemplated by this invention for this embodiment is that the first affixing means of the base body comprise first lower affixing means and first upper affixing means, wherein the first lower affixing means are located in a lower area of the cut or the sole, and the first upper affixing means are located in correspondence with the upper mouth of the cut, the second affixing means of the shells also comprising second lower affixing means that may be coupled to the first lower affixing means and second upper affixing means that may be coupled to the first upper affixing means. This way, the union between the shell and the base body in its lower and upper areas is ensured.

In another alternative embodiment of the invention, the base body may be configured by means of a sole incorporating the first affixing means, and the shells would be coupled by means of their second affixing means to the first affixing means of the sole, the footwear being thus defined by means of the coupling situation. This way, the shell would serve as the cut of the footwear.

Furthermore, and for any of the two embodiments, the possibility of the base body incorporating a flap that allows hiding the affixing means in the coupling situation between the base body and the shell has been envisaged.

The zippers, hook and eyes, magnets or others would be located between the affixing means used for the affixing of the shell to the base body, as well as the shape of the base footwear and the material of the shell that allow their coupling and affixing to the footwear. The affixing means used would be arranged in such a way that the so-called first affixing means would be arranged on the base footwear (either on the sole or on the cut), and the supplementary means, which we have called second affixing means, would be arranged on the exchangeable shells.

The footwear object of this invention therefore allows coupling different shells with different ornaments, designs, colors and/or models to the same base body in a simple manner, thus allowing the user to save by means of this solution, who would be able to use one base body combined with different shells to obtain different footwear. The foregoing also means a smaller occupation of space due to the shape and flexibility of the shell, which may be stored without using much space.

The proposed solution may also be combined with the possibility of connecting heels with different configurations and designs, according to the design of the shell, to the same base body. In that sense, the heel would incorporate a conventional affixing system, such as a screw, for example, which would be screwed to the base body in a simple manner, and would also be easily dismountable by unscrewing. This way, we propose the possibility of coupling a design heel matching the shell to the base body for a shell having a certain design.

The mounting and dismounting of the shell is carried out in a simple manner and allows coupling different shells with different designs, models, and/or colors to the same footwear, thus increasing the variation capacity of the footwear of a user at a very low cost and allowing said footwear to be comfortably stored in a very small space.
